In one aspect, a control plane Interworking Function (IWF-C) is used to establish a Packet Data Unit (PDU) session in a data communications network. A create session request is received, for example from a Mobile Management Entity (MME). A create session management context request is generated by the IWF-C and transmitted to a Session Management Function (SMF). A create session management context request response is received from the SMF. A create session request response is generated by the IWF-C and sent, for example to the MME. In other aspects, control plane policy interworking and user plane interworking is provided between components of 4G and 5G networks.

Core network functions

A telephony signalling element and method with a signalling processing function and a session datastore function. The signalling processing function has associated functions that are provided by one or more instantiations, and the session datastore function has associated functions that are provided by one or more instantiations. The instantiations allow for independent scalability of the functions in the telephony signalling element.
